On 8 January 2021, the UK Government and the Scottish Government both published statements concerning pre-departure coronavirus testing. Travellers arriving in England and Scotland from international destinations, including returning UK nationals, will soon be required to have proof of a negative COVID-19 test prior to arrival. This measure is being introduced to help protect against new strains of coronavirus circulating internationally.
The COVID-19 test must be undertaken a maximum of 72 hours prior to arrival back into England and Scotland. Travellers will have to make arrangements in the destination country to access testing. This measure is in addition to the need to self-isolate on return to the UK from countries not on the quarantine exemption (travel corridor) list.
